INTRODUCTION TO NEUROLOGY 



face looks somewhat like a sprig of the common evergreen cedar 

 tree known as arbor vitae. Hence this cut surface by the an- 

 cients was termed the arbor vitse. 



Fig. 89. Semidiagrammatic section taken transversely through a 

 lamina of the cerebellar cortex (Golgi method): A, Molecular layer, 

 filled with axons of granule cells cut at right angles to their course; B, 

 granular layer; C, white matter; a, Purkinje cell, with the dendrite broadly 

 spread out in the transverse plane (compare Fig. 15) ; b, basket cell (com- 

 pare Fig. 16); d, terminal arborizations of the basket cells enveloping the 

 bodies of the Purkinje cells; e, superficial stellate cells;/, Golgi cell of type 

 II (see p. 43); g, granule cells with their axons ascending and bifurcating 

 in the molecular layer at i\ h, mossy fibers; j, neuroglia cell; m, neu- 

 roglia cell; n, climbing fibers. (After Ram6n y Cajal.) 



The gray matter of the cerebellum is partly superficial (this 

 is the cortex to which reference has already been made) and 

 partly in the form of deep nuclei embedded within the white 

 matter. The largest of these deep gray centers are the dentate
